The GFCIs look grounded to my tester. I haven't bothered to open them up and look if there is a ground wire in there. What I was trying to say is that all of the "normal" (non-GFCI) 3 prong outlets are just hot and neutral with no ground wire in there. Landlord did the cheap thing, although I don't know of any easy and inexpensive way to retrofit a ground in to a lot of outlets (say 20+).
As for my sub-panel and 3 phase panel things, I've just ordered a 500' spool of #1 aluminum wire. It is _WAY_ less expensive than copper. I will be certain to read up and make certain that I bond everything correctly, use anti-corrosion goo and make certain all connections are torqued down properly. The RPC and all of the machine loads will be made using some copper THHN that I already have.
I've acquired a Cutler Hammer 3BR1224L125 125 amp 3 phase circuit breaker load center panel and now I need to find some CH BR3xx plug/ stab-in breakers. 3 pole breakers are pricey new! Anybody have some Cutler Hammer compatible breakers like these: BR360 BR350 BR340 BR330 BR320 BR315 BR310
Thanks!
